Lysosomes are membrane-bound organelles whose acidic lumen (pH 4.5–5.0) is required for degradation. This luminal acidity is ...

Researchers at the Icahn School of Medicine at Mount Sinai have characterized how cellular senescence—a biological process in ...

An implantable scaffold and magnetic probes capture circulating tumor cells directly in the bloodstream, eliminating over 90% of captured cells in rabbits and goats.

Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic ...

The kidney's proximal tubule reabsorbs water, glucose, ions and other small molecules from the urine and thus maintains the ...

Platelets are small, anucleate blood cells that play an essential role in hemostasis. Their primary task is to recognize vascular injury, become activated, and aggregate via their surface receptor ...

A healthy digestive tract is the key to good health. The digestive process is complex and the digestive tract is designed to ...

Brazilian researchers have identified previously unknown forms of a protein linked to breast cancer. The discovery ...

A new study by researchers in Japan offers new insights into how protocells may have inherited and enriched genetic material before modern biology emerged. By exposing mixed phospholipid vesicles to ...

Proteomics experiments on Drosophila reveal sex-specific effects in aging, and an important role for a protein called DIP-β.

Scientists have identified the role of an ion channel that plays a key part in how cells break down and recycle components, a discovery that could open the door to new treatment strategies for ...

Cilia are evolutionarily conserved, microtubule-based organelles that project from the surface of most eukaryotic cells and play a central role in sensing ...
